12 Years from now, the modern republican party will be split or dead.
A split is likely with massive moves in the nation to the left leading to huge Democcratic majoritys in the house and Senate not seen since FDR! That extreme filibuster action from the GOP is the act of a desperate group watching their voting base shrink rapidly. We might not see another Republican President for 30 years or more if ever.
A more centerist NEW party is more likely to gain power then the rightwing nutcase GOP.
A split might also moderate the Democratic party back to the center. The Dem center move left in order to get the votes of the extreme left. A group of moderate Republicans could do more to move the country toward the center/right than anything else ..... WHOA ...... Twitter board .... a TWO line peephole message posting window.
